NIPPERS.

To all whom it may'concem Beit known that I, VEEZEY E. BowMAN,

I a citizen of the United States, residing at McKees Rocks, in thecounty of Allegheny and State ofA Pennsylvania, have invented certainnew land useful Improvements in Nippers, of whichthe following is aspeciiication.

This invention relates to new land useful improvements in a deviceknown. in police parlance asV nippers, and the primary object thereof isto provide a device of the,

character described to facilitate the subjection andcontrol of an unrulycaptive or prisoner by the officer of the law.

Other objects of this invention are to pro-y vide a device ofthe typesetforth which is spring operated tolock upon the wrist of a theaccompanying drawings wherein is shownV an embodiment of the invention.

In the drawings forming aportion of this specificationand wherein likenumerals of reference designate corresponding parts I throughout thevseveral views:

Referring more in `detail to the drawings there is shown in Fig. 1 thenippers embodying the invention and comprising the casing 1 having theneck 2 vformed integrally therewith. The arm 3 is securely fixed in thecasing 1 byvmeans ofthe rivets 4 and carries the locking chamber 5.

The gripping handle 6 is formed vintegrally with the stem 7 which isprovided with the thread 8 adapted to engage in the threaded aperture-9in the neck 2. A collar 10 is fixed on the stem 7 in the casing 1 tolimit the upwardmovement of the stein 7 in the threaded aperture 9.

The aw 11 is pivotally mounted at. 12 in the casing 1 and is providedwith the serrated end 13 which is adapted to ybe engaged by the lockspring 14 in the locking chamber 5.

The curvature of thelower portion 15 of the casing lcombined with thecurvatures of the arm 2 and the jaw 11, are suchthat the combinationconforms as nearly aspossible to the contour of the average wrist.

The Voperating rod 16, pivotally connected at 17 to the jaw 11, extendsvertically through the aperture 18 in the top of the casing 1 andisformed with the ring 198L for the insertion of the finger whenoperating.

the device. The spiral spring 19mounted on the operating rod 16, isnormally in the expanded position and tends to force the jaw 11 to thelocked position in the locking chamber 5.

The lock spring 14 is riveted yat 20 to the locking chamber wall 21 andVengages the serratedend 13 of the j aw 11 when the latter is forced intothe locking chamber 5 by the action of the spring 19 or by the manipulation of the gripping handle 6. The spring 1,4: is disengaged fromthe serrated end 13 of the jaw 11 by the useof a key (not shown) whichis adapted to operate through the key-'hole 22.

For the purpose of holding the spring 14; disengaged from the serratedend 13 of thej aw 11, when the nippers are not in use, therev isprovideda pin 23 XvedlyA riveted Y disengaged by means of the key which forcesthe catch 24 out through .the chamber wall 21. The catch 24 beingswiveled to the p1n 23 is given a turn to extend at rght-anglev withrespect to the slot 25 and will hold the spring 14 in the inoperativeposition until f the catch 24 is again turned to extend-parallel to theslot 25. Y

The stem 7 has a swivel connection with the tightening cam 26 in thecasing 1. The tightening cam 26 is mounted for vertical movement in thecasingl by therotation of the stem 7 in the threaded aperture 9 in theneck 2. The tightening Vcam 26 is provided with the beveled end 27 whichis adapted to engage the vertically extending fbev'eled end 28 of thejaw 11 and force the jaw -11 tightly around the wrist of the prisoner.vThe: end 29 ofthe tightening cam 26V acfsfagainst the arm 3 whichserves as a guide therefor.

ln practice'theoperationV offthe device isas'followszffhe officer of thelaw iirst throws the catch y24 to bring the spring 14 to the operativeposition. He then grasps the grippinghandle 6 with one finger in thering'19av and pulls the operating rod 16 upwardly toward the handle 6which opens the jaw 11. The jaw 11 is'` thrown or placed upon the wristof the prisoner and the ring 19a released which will cause the spring'19to force the'jaw 11 to the closed vor locked position inlthelockingchamber 5'. e v

I-f theprisoner proves unruly afterthe device is placed on 'his' wristas herein above described,V the officer gives the gripping handle 6 aturn which forces the cam 26 downwardly to actv against the beveled end28 of the jaw 11 and forces the jaw'still more tightly around the wristof the pris In the modification shown in Fig. 6 of the drawings, twovjaws 3.0 and 31, pivotally mounted in the casing 32 at 33 and 34,respectively, are providedwhich are simultaneously operatedl bytheoperating member 35, which comprises therods 36 and 37 encircles theneck 42'of theV casing 32.

pivotally connected at 38 and 39 to the jaws 30 and 31. The rods 36 and37 are securely fixed to the cross-bar 40 which is provided with thecentrally located opening 41 whici ring 43 is' mounted yon one side ofthe crossbar 40 forV manipulating the operating member 35. Spiralsprings 44 and 45 are respectively mounted on therods 36v and 37 for thepurpose and forcing the jaws 30 and 31 to the closed position. A groove46 is formed in the neck 42. inv which is mounted a. notched spring47.by the rivet V48.' The spring 47 normally stands outward from the groove46 as shown in Fig.V 9 andis` adapted to engage the upper face of thecross-bar 40 and prevent the upward move-v ment of the operating member35fand lock the jaws 30 and 31 upon the Wristof the prisoner. Foropening the jaws 30 and 31V the spring 47 is forced vintoi-the groove 46by pressure upon thebutton 49 while drawing the operating member 35upwardly.l v

yThe cam 50, having a swivel connection with the `stem 51, isprovidedwithV the beveled ends 52 and 53 which .engage the re- Y specive jawends 54 and 55, and when movedY downwardly bythe rotation of the stem.51 causes the jaws 30 and 31 to close tightly upon the wrist. The jawen ds 56 and' Y57 instead of abutting as shown in Fig. 6, may' loe madewith respective interfitting male and female ends.

Suitable cover plates are provided for the casings in the preferredandmodiiied-forms of thev device and may be either riveted or fastenedwith vscrews as desired.v

- It will be noted that therespective casin s are provided with slots topermit the lample* Vmovement of the jaws therein, i j

From the foregoing description taken in connection with the accompanyingdrawings, the advantages of the constructionand the method of operationwill be readilyappa'renty to those skilled in the artto whichtheinvention appertains, and while describing the principle of Voperationof the invention together with the device which is `now con-VV sideredto be the best embodiment thereof,

it is to be understood that the device shown v -1 is .merelyillustrative and :that various changes in the form, proportion :andthe vminor details Vof construction may :be resorted to without departin fromthe @principlle or sacrificing any oft e advantages of ing a lockingchamber fixe'dlymounted in the said casing, a jaw p ivotally mountedfinthe said casing, an operating rod, a spring for Vautomatically lockingthe said jaw'in the said locking chamber mountedV on ,the
